Revision summary
Visvesvaraya: KRS dam, automatic weirs, Hyderabad flood works, and water for industry. He framed public works and planned industrialisation around stored water. Swaminathan: dwarf wheat, IARI/ICAR, and escape from PL-480 dependence. The National Commission on Farmers linked MSP, insurance and irrigation to livelihood. Evergreen revolution is his caution: yield with soil and groundwater, not only more canals.

Introduction
Sir M. Visvesvaraya and Dr M. S. Swaminathan sit at two ends of India’s food-and-water story: storing and directing river water, then breeding and advising so that water and seed become grain. One built dams, weirs and industrial water use in the princely and early national period. The other led the wheat revolution and later argued for a farmer-centred evergreen path.
Body
Visvesvaraya and water engineering
- As Chief Engineer in Mysore he designed the Krishna Raja Sagara (KRS) reservoir on the Cauvery: storage for irrigation, drinking water and later hydropower around a water-scarce plateau.
- He invented and deployed automatic weir floodgates (patented block system) so reservoirs could hold more without sacrificing flood safety — a direct engineering answer to monsoon peaks.
- After the 1908 Musi floods he planned modern drainage and reservoir protection for Hyderabad, cutting the city’s flood vulnerability.
- He linked water to industry: Bhadravati iron works, planned towns, and a belief that engineers and factories must follow irrigation. That is an early Make in India instinct: water as productive capital, not only a canal for subsistence.
- As Dewan of Mysore and later a Bharat Ratna (1955), he spread the idea of planned public works. India’s later Damodar, Bhakra and Nagarjuna Sagar generation walked a road he had already mapped: store, irrigate, industrialise.
Swaminathan and agricultural science
- At IARI and in partnership with Norman Borlaug’s dwarf wheat, Swaminathan adapted high-yielding varieties to Indian photoperiod and rust, which made the Green Revolution in Punjab, Haryana and western Uttar Pradesh possible in the late 1960s.
- India moved from ship-to-mouth wheat imports under PL-480 toward self-sufficiency. That is a national-security as well as a farm gain.
- He built institutions: ICAR leadership, training, and the M. S. Swaminathan Research Foundation on coastal and tribal livelihoods, biodiversity and women farmers.
- The National Commission on Farmers (2004–06), which he chaired, set the still-cited MSP at C2 plus 50 per cent recommendation and stressed irrigation, credit and crop insurance — the policy ancestors of PM-KISAN, PMFBY and irrigation missions.
- He warned early that the first Green Revolution had groundwater, soil and nutrition costs, and called for an evergreen revolution: more yield per unit of water, not only more water.

Conclusion
Visvesvaraya gave India the engineering grammar of storage, floodgates and industrial water. Swaminathan gave it seed, institutions and a farmer-commission agenda so that stored water becomes food. Together they show that production is dams plus biology plus a fair price, not one hero crop.

-
Did Swaminathan only raise wheat yield?
Yield was the 1960s task. His later work is biodiversity, women farmers, coastal systems, and the NCF price-and-insurance agenda.
-
Is Visvesvaraya relevant after PMKSY?
Yes. Micro-irrigation still needs storage and flood design. His weirs and KRS logic sit under every modern irrigation mission.

What are the challenges to solid waste management in India? Discuss the governmental policy framework on solid waste management. Discuss the success/failure cases of Delhi and Indore cities highlighting the salient features of their solid waste management initiatives.
Indian Economy
• Rapid urbanization has made solid waste management a critical environmental and public health crisis in India. • Key challenges include lack of source segregation, inadequate processing infrastructure, reliance on unprotected informal workers, and financially weak urban local bodies. • The policy framework relies on the SWM Rules 2016, Swachh Bharat Mission (Urban), and Plastic Waste Management Rules 2016. • Indore succeeded through 100% source segregation, zero dump-site remediation, and strict enforcement with digital monitoring. • Delhi failed due to overloaded legacy landfills (Ghazipur, Bhalswa), lack of decentralization, and fragmented municipal governance. • A successful transition requires moving to a circular economy focused on source segregation, decentralized processing, and polluter accountability.

What is Agentic Artificial Intelligence (AI)? Explain its working. Describe its applications with suitable examples. Discuss the advantages, risks and challenges associated with agentic AI systems.
Indian Economy
Agentic Artificial Intelligence represents an advanced paradigm where AI systems operate with autonomy, setting goals and executing complex workflows without constant human prompts. Unlike traditional generative AI that merely responds to queries, agentic AI uses perception, planning, memory, and tool-use to achieve multi-step objectives. Its applications span across autonomous software engineering, supply chain optimization, and automated financial trading. While offering massive productivity gains and dynamic problem-solving, these systems pose significant risks including lack of transparency, alignment failures, security vulnerabilities, and ethical dilemmas. Governance frameworks and robust guardrails are essential to harness their potential safely.

Mention salient features of 'Mission Drishti'. Discuss the imaging techniques used in the satellite launched on 3rd May 2026. Why is it being considered world's first satellite of its kind?
Indian Economy
Mission Drishti represents a major leap in India's space-based Earth observation capabilities, launched on 3rd May 2026. The mission employs advanced multi-spectral and hyperspectral imaging techniques to capture high-resolution data across various atmospheric and terrestrial layers. It is hailed as a global first due to its unique integration of real-time onboard edge computing with quantum encryption for secure data transmission. The satellite significantly enhances resource management, disaster response, and strategic surveillance. It aligns with India's policy of leveraging space technology for sustainable development and national security.
